times greater than the rate of planting here- ,toii'ore obtaining in the use of conventional horse drawn check-row planting equipment. An object of the inventionis to provide an improved check wire anchor capable of cooperating with a four-row tractor planter to produce accurate checking of corn,-

The invention is illustrated by the accompanying drawings, inwhich:

Figure 1 is a side elevation of the check Wire anchor located in a position substanti ally corresponding to operative position;

Figure 2 is a plan of the cheek wire anchor shown in Figure 1;

, Figure 3 is a front elevation of thecheck Wire anchor; j

Figure 4: is a'diagrammatic View illustrating the action taking place during the checking'of a field;

Figure 5 is'a diagrammatic view illustrating the first step in the method of using the illustrative equipment; and s Figure eis a detail diagrammatic view; illustrating a step in the use ofthe'illustrative equipment, subsequent to the step illustrated in Figure 5;

P Referring to Figures 1, 2 and 3 of the drawings, the illustrative check wire anchor includes, the reciprocable guide '1" straddling the usual =end stake 2'. The guide is pref erably formed of a single rod bent toprovide a loop 3, the parallel members 4;, and the hooks 5. As clearly shown .-in-Figure 2 of the drawingsthe'inembers 4 are for wardly convergent at a position indicated at 6. Forwardly of thisposition these menibers are substantially parallel and-placed in proximity to each. other; They aretrigidly held in thisposition by'a clamp 7 remove ably secured in positionby the bolt 8.

Forwai'dlyof the clamp 7 the'ends of the members 4. are' bent upwardly to' form the 11' in operative position.

readily secured to the anchor by inserting the wire within the 'upwardly diverging hooks,- the enlargement or: button of the check wire" engaging'the hooks on the side toward the end stake 2.

' For permitting necessaryflexibility of the CORPORATION anchor, so that it may'adapt itself to vari ous conditions obtaining at different periods during'theuse of the illustrative equipment, 7' the end stake 2 is-joi'nedto the clamp 7 by yielding means herein shown as afcoil' spring 9 preferably surrounding and enclos- ,ing the members 4. ,One looped end 10 of the coil spring receives the end stake, as

clearly illustrated in Figures l and 2. The

other loopedend 1 1 of the coil spring is placed over the forwardly converging partsof the clamp 7, -the ends of whichserve as abutments to, lock the loopedjend Figures 1 and2 of the drawings illustrate anchor when the spring is under tension, this condition beingnormally created by the hooking ofthe check wire 7 within the hooks ;5 when the check wire is stretched across a field to be planted, It-will be evident that a decrease in the pull of the thefrelative positions of the parts of the check wire will result in the movement of the hooks 5' toward the stake" 2' by reason j I v or the contractile effect orthe spring 9. Sii'nilaily, any increase in. thepull of the check-wire upon the anchor will result in creasing of the distance between the stake 2 and the clamp 7;. 'In the presentinvention 1 the expansion of the spring9 and the iii-p as about'f6' to 8 inches during the check ing operation;

During 'the operation of the illustra'tive' equipment an anchor is secured at each of the positions indicated'at' 12 and 13in Figure 4 of therdrawings, at 14in Figure 5 of the drawingspand at Hand-16in Figure 6-of 7 the drawings.

Figure 4 of the drawings illustrates conditions oi. the equipment during the starting of any trip across the field during the plant ing, check Wire anchors being secured at positions 12 and 13.

Referring to Figure 4.,ofthe drawings, the planter is shown advancing in the di The check Wire d6 ends of the field. .During such action it is necessary for theplanter .to move the check ivire transversely of the field a distance in- In doing so,the"

musthe moved by the planter a considerably greater distance.
